Bullet Sorting

I've always heard that you will get better reloading precision if you use components from the same lots. Is this practice not relevant if you sort by weight and bearing surface?

In other words, if I were to dump 1000 rounds from different lots into a container and then weigh and sort them by bearing surface, wouldn't I get more consistency than if I keeps the lots together and used lot numbers as my sorting criteria?

Yes, I think this might provide better results.

I sort by bearing surface, then sort those groups by weight. I use the extremes from these as foulers. I keep the others in groups based on bearing surface and use them in groups.

I took the .612 and .617 for the fowler pile. Then sorted the remaining pile into weight groups that were +/- 1 gn. Didn't have many weight groups though as the bearing surface had the most variation with this group of bullets. All 300 were from the same lot.
